The house sparrow is unique, because almost everyone in the world is familiar with this little bird. It is below 20 cm in length, with a feather cover of grey and brown shades.
These birds can live in mountainous and plain terrains alike. They are very social by nature and roost communally. They build nests in holes in walls and ceilings, with straw and garbage.
They basically eat seeds and grains, randomly collected from the ground. But these birds can assemble in large numbers and can raid crops, causing very serious damage to cultivations. They do this especially during winter seasons.
Also, due to their habit of destroying flower buds and vegetables they are often a headache to people cultivating kitchen gardens. They have a large number of enemies including cats and owls.
